An object with a mass of #4 kg# is acted on by two forces. The first is #F_1= < -7 N , 4 N># and the second is #F_2 = < -3 N, -2 N>#. What is the object's rate and direction of acceleration?
The first force vector acting on the object of mass
The 2nd force vector acting on the object of mass
So the resultant force
So the acceleration
Hence the magnitude of acceleration is
And its direction is
